Vince Lombardi once said, “Only perfect practice makes perfect.” True for football, also true for golf. Weighted golf clubs have been a hot training aid for years, but who wants to practice with a club they aren’t actually going to play with? Taylormade’s TR3 Speed Sleeve ($30) does just that, transforming any club in your bag to a heavy club for practicing. Best of all you can hit balls with it attached. Once in place, you’ll feel the club’s weight throughout the swing, which helps prevent your arms or hands from unnecessarily manipulating the club. Learning to swing more with your body instead of your arms will add both consistency and lag to your swing. Try it on your putter or around the green to fine tune a buttery, smooth short game tempo.
